Discussion
Collinsia linearis and C. rattanii occupy similar habitats, often growing in rocky soil derived from mafic, volcanic rock. They form a lineage but may not be reciprocally monophyletic (B. G. Baldwin et al. 2011). Other than differences in corolla size and shape, and, possibly, seed morphology, they are extremely similar. Corolla shape (floor of throat angled 45° to 60° from abaxial side of calyx and reflexed portion of adaxial lip length 1.5 to 2 times throat) and smaller corolla size are characteristic of C. linearis. Some plants from this lineage, mostly from Oregon, are difficult to assign to either C. linearis or C. rattanii.
